"line break" disapears in text box after resizing the form

[Philip.Arbin]

I put a text box on a form and set it to "multi line".
I use it to show some log information.

Every time there is some information, I use TextBox.AppendText method to add
a information string and a "\n" into the text box. There will be a line
break after the infromation string for the "\n" charactor.

But after i resized the form or click some other window on the task bar and
switch back, the line break disapears. All the text turns into only one
single line.
Is there something wrong using "\n" in multiline text box?
Is there any solution for this issue? or I should use richtextbox or detail
listview instead?

Hi,

Thank you for posting.

I have created a simple WinForm project containing a form for testing. I
put a textbox and a button on the form and set the MultiLine property of
the textbox to True. I added an event handler for the button's click
event. In the button's click event I used the AppendText() method of the
textbox to add a string into the textbox. I used a "\n" to add a line break
and there was a line break for the "\n" charactor. However I didn't see
the problem that the line break disappeared and the text in the textbox
turned into only one single line after I resized the form or clicked some
other window on the task bar and switched back. The line break still
existed.

Maybe you could have a try to use "\r\n" to add a line break.

Hope this is helpful to you.
If you have any other concerns or need anything else, please don't hesitate
to tell me.

I tried it again and found it happens under this condition:

-- if the textbox's "anchor" propertise is set to "left, top, right";

then i realize that this will happen when you resize the textbox, not the
form.

And i tried the "\r\n", it works.

thank you very much.
